It's the same as the other tt keyboards. Though I agree, it's hard to find keyboards with macro keys!
I can tell you from experience with those keys work wonders for sc2 and other competitive online games. It will allow me to move away from the horrendous Naga mouse and switch to a much more accurate mouse without the extra keys on the Naga. With those extra macro keys I'm able to reach the 6-0 keys without moving my left hand at all (reprogramming the macro keys to 6-0). It's the same reason why I kept my Logi G15 for the entire time when I've went through three Filcos, and an I rocks mechanical keyboard.
